S.S.W. Near 10 the ochraceous schists recur dipping under a 
large vein mass of milky quartz at 15°-20°S.S.W. South of 
10 about 75 feet of finely laminated, carbonaceous slates dip 
30°-40° W.N.W. At 11 these dip 45° W.N.W. and continue 
to Sheep Point and 12, 13. Professor C. H. Hitchcock gives 
18 species of coal plants from this bed and two seams of an- 
thracite, 6 inches and 12 inches thick, now probably concealed.* 
At 12, these schists dip 40° W.N.W. and contain ferruginous 
nodules several inches thick, minute veins made up of alter- 
nating lamin of quartz and anthracite, and give rise to a 
erruginous spring; at 18 they terminate with a high inclina- 
lon, The next outcrop along shore (about 25 feet off) consists 
of a soft, decomposed, light gray, argillaceous or talcose schist 
@pping at high angle westerly, about 45 feet thick, passing 
Into a harder, greenish, talcose schist which passes into a tough, 
dark gray, slightly purplish, coarsely schistose argillyte with 
minute veins of serpentine and passages of calcite. This rock 
forms the headland, 14, and, at 15, passes into an argillaceous 
Serpentine with occasional layers of chloritic talcose schist, 
nodules and veins of e idote, passages of chlorite and bot 
“tge and minute veins of quartz, dipping about N.N.W. The 
islet and rocks to the east seem to be of the same character, 
thus bringing the’ easternmost exposure of this bed on a line 
With Ochre Point. On the south it continues to 16, where it is 
Mm close contact with protogine, hand specimens showing both 
rocks together. This protogine forms the whole point and 
Coggeshall’s Ledge, in places is characterized by large crystals 
of feldspar, according to Professor E. Hitchcock by faulted 
Veins,+ at one locality is traversed by a vein? of yellowish ser- ~ 
Pentine, and at 17 near Bailey’s Beach underlies the epidotic 
4nd chloritic schists again. These may be traced to 18 and 19. 
‘ay contact occurs in this wise at 17: Lying immediately upon 
whole length of Levin street, pt. 23. They are ee argilla- 
“cous and perhaps micaceous schists, with thickly di oB° 
Tate grains of, a ferruginous mineral, and dipping about 20
